gnulib-tool.sh: Accept conditional dependencies with tests

[Bruno Haible]

One of the newly added tests fails like this on the shell side:

$ GNULIB_TOOL_IMPL=sh ./test-cache-2-26.sh
gnulib-tool: option --conditional-dependencies is not supported with 
--with-tests
FAIL: gnulib-tool exited with code 1.
$ GNULIB_TOOL_IMPL=py ./test-cache-2-26.sh
diff: ./test-cache-2-26.result: No such file or directory
FAIL: gnulib-tool's result has unexpected differences.

The error "option --conditional-dependencies is not supported with --with-tests"
is not longer justified since the 2017-12-28 patch. (There were two instances
of this error message, and I mistakenly removed only one of them.)

This patch fixes it.
